设置WDS

TP-Link WR740N 和 TP-Link WR703N 组成WDS

• WDS的原理

• 设备

  1. TP-Link WR740N, 为原生系统, 作为主路由. MAC:14:E6:E4:31:8E:F2, SSID: Holy
  2. TP-Link WR703N , 已刷OpenWRT, 作为client路由. MAC: 8c:21:0a:da:99:36, SSID: OpenWRT

• 准备工作

  1. 设置主路由.
     登录到路由管理界面,找到无线设置--> 基本设置
     设置好SSID, 信道选特定的值,可以随意,总之要具体的值.
     开启WDS功能, 扫描目标路由. 找到你的目标, 选14:E6:E4:31:8E:F2加密方式, 填密码, 具体如下图.

  主路由设置完毕,需要重启才生效.

1. 设置client 路由.

ssh 进去 openwrt系统.
配置主要参考这里

一共是4个文件需要修改, 分别是

• /etc/config/network #修改ip 为192.168.1.2
• /etc/config/wireless #主要的修改之处, 见下文
• /etc/config/dhcp # config dhcp lan 处 添加option ignore 1, 即client禁用dhcp功能
• /etc/config/firewall # config zone lan 处 修改 option forward 值为 ACCEPT.

/etc/config/wireless

root@OpenWrt:/etc/config# cat wireless

/etc/config/dhcp

config dhcp lan
    option interface    lan
    option start    100
    option limit    150
    option leasetime    12h
    option ignore   1

config dhcp wan
    option interface    wan
    option ignore   1

/etc/config/firewall
文件内容比较长,这里贴出主要内容.

...

config zone
    option name     lan
    option network      'lan'
    option input        ACCEPT
    option output       ACCEPT
    option forward      ACCEPT  
...

最后, 重启client 路由器. 如无意外, 手机连接到client路由器(本身是没有插网线的), 发现可以上网了 !!!

个人对原理不太懂, 于是有个疑问, 为什么在client路由上ping 不了外网呢,比如 baidu.com ?
